The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
I collected this female spinner together with a male dun, a female dun, and another male dun.
This mayfly was collected from Mystery Creek #23 in New York on September 6th, 2006 and added to Troutnut.com by Troutnut on October 3rd, 2006.
